Abstract (en)
The present invention provides a storage device and a data processing method of the storage device which can prevent leaking of data attributed to stealing or taking out of a disk device. A storage device includes: a plurality of disk adapters each of which is connected to HDDs which constitutes at least one RAID group; and a management part which manages a storage area provided by the plurality of HDD in a state that the storage area is divided into a plurality of logical storage areas, and manages the plurality of RAID groups. The management part sets an encryption state indicative of whether or not the data is to be encrypted with respect to the RAID group when all of the disk adapters connected to the HDD which belong to the RAID group are the encryption adapters the data, and the encryption adapter encrypts, based on the encryption state set with respect to the RAID group, and stores the encrypted data in the HDD.
